NATIONAL WEATHER SERVICE CARIBOU ME
343 AM EST MON DEC 31 2007
.SYNOPSIS...
LOW PRESSURE DEVELOPING ALONG THE MID ATLANTIC COAST WILL
INTENSIFY AS IT QUICKLY TRACKS SOUTH OF THE GULF OF MAINE AND THEN
SOUTH OF NOVA SCOTIA TODAY. SNOWFALL WILL ACCOMPANY THIS SYSTEM
ESPECIALLY OVER CENTRAL AND DOWNEAST AREAS TODAY. HIGH PRESSURE
WILL BRIEFLY BUILD ACROSS THE REGION TONIGHT AND TUESDAY BEFORE
ANOTHER LOW PRESSURE TRACKS THROUGH THE GULF OF MAINE WITH
ANOTHER ROUND OF SNOWFALL FOR TUESDAY NIGHT INTO EARLY WEDNESDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
ONLY CHG MADE TO ONGOING EVENT WAS TO EXTEND HVY SN WRNGS A LITTLE
FURTHER N TO INCLUDE ZONES 5...6 AND 10. THIS IS BASED ON THE
POTENTIAL OF HIGHER SN RATIOS OCCURRING OVR THIS AREA WITH DEEP
LIFT AND NEAR ZERO EQIV POTENTIAL VORTICITY COINCIDENT THRU THE
DENTRYTIC CLD ZONE...OFFSETTING LESSER QPF AMOUNTS XPCTD OVR THIS
AREA. SN RATIOS USED VARIED FROM 12 TO 1 ALG THE COAST...WHERE
NEAR FZG SFC TEMPS AND SOMEWHAT GREATER WINDS WILL RESULT IN MORE
PACKING OF THE DENDRYTES AFTER STRIKING THE GROUND...UP TO 18 TO 1
ACROSS THE NRN HF OF THE FA WHERE TEMPS AND WINDS WILL REMAIN
SUFFICIETLY LOW ENOUGH TO PREVENT FRACTURE AND COMPACTION OF THE
DENDRYTES.
MODELS INDICATE BEST DYNAMICS ENDING 18Z TO 20Z W TO E ACROSS THE
FA AS THE OPEN 500 MB TROF AXIS QUICKLY PROGRESSES THRU THE FA...
AT WHICH TIME SNFL SHOULD QUICKLY WIND DOWN TO SCATTERED SN
SHWRS/FLURRIES AND THEN END BY ERLY EVE. SKIES SHOULD AT LEAST
PARTIALLY CLR INITIALLY OVER DOWNEAST AREAS THIS EVE SPREADING NE
INTO NERN AROOSTOOK COUNTY BY LATE TNGT. ONLY MODESTLY COLD AIR
FOLLOWS THIS SYSTEM FOR TNGT...BUT THERE COULD BE A WINDOW FOR
SOME RADIATIONAL COOLING LATE TNGT AS WINDS DROP OFF.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
BASED SHORT TERM FORECAST ON THE GFS WHICH HAD GOOD COLLABORATION
WITH THE UKMET AND SREF. MODELS TRENDING SLOWER WITH NEXT
LOW PRESSURE REDEVELOPING OFF THE NH COASTLINE TUESDAY EVENING.
SHORTWAVE RIDGE IN ADVANCE OF THIS NEXT UPPER TROUGH SHOULD
PROVIDE A DRY FORECAST FOR MOST OF THE DAY ON TUESDAY. WITH
REDEVELOPMENT OFF THE NORTHERN NEW ENGLAND COAST TUESDAY EVENING,
SNOW WILL SPREAD ACROSS THE REGION TUESDAY EVENING. AS WITH
CURRENT SYSTEM, HIGHEST QPF, THUS HIGHEST SNOWFALL AMOUNTS, WILL
LIKELY BE OVER CENTRAL AND DOWNEAST SECTIONS TUESDAY NIGHT. SNOW
TO TAPPER TO SNOW SHOWERS WEDNESDAY AS LOW PRESSURE TRACKS SOUTH OF
NOVA SCOTIA BY WEDNESDAY EVENING. IF CURRENT TRENDS CONTINUE,
WINTER STORM WATCHES MAY BE NEEDED FOR CENTRAL AND DOWNEAST ZONES
FOR TUESDAY NIGHT.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
BASICALLY USED THE GMOS FOR THE EXTEND WITHOUT MAKING ANY
SIGNIFICANT CHANGES. AS LOW PRESSURE MOVES EAST OF THE REGION
WEDNESDAY NIGHT, ARCTIC AIR WILL FOLLOW ON ITS HEELS FOR WEDNESDAY
NIGHT AND THURSDAY UNDER A BRISK NORTHWEST FLOW. STRONG
NORTHWEST WINDS COMBINED WITH BELOW ZERO TEMPERATURES MAY PRODUCE
WIND CHILLS COLDER THAN 20 BELOW WEDNESDAY NIGHT FOR NORTHERN
SECTIONS. THE ARCTIC HIGH WILL GRADUALLY BUILD ACROSS THE REGION
THURSDAY AND CREST THE AREA FRIDAY. AS THE HIGH MOVES SOUTHEAST
OF THE REGION THIS WEEKEND, SOUTHERLY FLOW ON THE BACK SIDE OF
HIGH WILL ALLOW TEMPERATURES TO SLOWLY MODERATE.
&&
.AVIATION /07Z MONDAY THROUGH FRIDAY/...
MSLY IFR IN CLGS AND SNFL THIS MORN AND ERLY AFT ACROSS ALL TAF
SITES...IMPROVING TO MVFR LATER THIS AFT AND THEN VFR OVRNGT WITH
DOWNEAST TAF SITES LEADING THE IMPROVEMENT A FEW HRS OVR NRN TAF
SITES.
EXPECT VFR CONDITIONS TUESDAY BUT CONDITIONS WILL LOWER TO IFR IN
SNOW TUESDAY NIGHT. CONDITIONS WILL GRADUALLY IMPROVE TO MVFR AND
EVENTUALLY VFR WEDNESDAY AS SNOW TAPPERS TO SNOW SHOWERS AND ARCTIC
HIGH BUILDS INTO THE REGION. ARCTIC HIGH WILL PRODUCE VFR
CONDITIONS FOR THURSDAY INTO FRIDAY.

.MARINE...
WILL KEEP WITH SCA...BUT CANNOT RULE OUT A VERY BRIEF PD (LESS
THAN 3 HRS) OF LOW END NRLY GALES OVR OUTER WATERS MID TO LATE AFT AS
THE LOW INTENSIFIES MOVING INTO THE MARITIMES...AND THE BACK SIDE
MSL PRES GRADIENT INCREASES. WIND SPEEDS SHOULD DIMINISH THRU SCA
RANGE THIS EVE WITH ONLY SCA SEAS PERSISTING ACROSS OUTER WATERS
LATE TNGT.
SHORT TERM: QUITE OVER THE WATERS TUESDAY AS HIGH PRESSURE RIDGE
CRESTS THE WATERS. SOUTHEAST WINDS WILL INCREASE TO SCA AND
POSSIBLE GALE FORCE LEVELS AS LOW PRESSURE REDEVELOPS OFF THE NH COAST
TUESDAY NIGHT. THIS LOW PRESSURE WILL TRACK OVER THE WATERS ON
WEDNESDAY AND THEN AS LOW PRESSURE MOVES EAST OF THE REGION,
ARCTIC AIR WILL FOLLOW LATE WEDNESDAY WITH POSSIBLE NORTHWEST GALE
FORCE WINDS.
